As a specific aluminum profile, aluminum bblate is an aluminum profile with a specific cross-sectional shape. Its cross-section is usually flat with a rounded (or "spherical") edge. This shape design helps to enhance its structural strength and stability.

Marine Grade Aluminum Bblate Bar is an extruded solid aluminum, popular choices for marine applications when a lighter weight is needed, and corrosion-resistance is a concern.

Aluminium Bulb Flat Bar is mostly used in the marine industry, both in the initial construction as well as the working life phase. Its rounded shape enhances drainage, and minimises dirt and moisture traps. There is also no need for edge grinding. It delivers buckling resistance at a lower weight than flat bars or angles.

Common alloys of aluminum bblate include 5083 aluminum alloy, 5086 aluminum alloy, 6061 aluminum alloy, 5456 aluminum alloy, etc. It is an essential raw material for shipbuilding, bridges and some marine engineering. Marine aluminum bblate is a special profile for the shipbuilding industry. It is used as a ship hull reinforcement rib and plays an important role in the ship's carrying capacity and safe navigation ability.

Extrusion production process of aluminum bblate:

The production of aluminum bblate usually adopts the extrusion process, that is, the molten aluminum liquid is extruded into the required cross-sectional shape through a specific die. During the extrusion process, parameters such as temperature, pressure and speed need to be strictly controlled to ensure the quality and performance of the product.

1. Surface pretreatment: Use chemical or physical methods to clean the surface of the profile to expose the pure matrix so as to form a complete and dense oxide film. Mirror or matte effects can be achieved mechanically.

2. Anodizing: Under specific process conditions, the pretreated profile surface is anodized to generate a dense, porous and highly adsorbable Al2O3 film layer.

3. Sealing: Seal the pores of the film after anodizing to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is transparent and can achieve a variety of colors such as black, bronze, golden, etc. by adsorbing metal salts.
